Debugging the Project

The Nios II IDE contains an integrated debugger that allows you to debug your program on

Nios II hardware or on the instruction set simulator (ISS) . This topic introduces the main

features of the debugger. The tutorial assumes you are working with a Nios II hardware

target. The process is the same for debugging on the ISS, with the exception of steps that

involve the target hardware.

Note: When debugging on Nios II hardware, the FPGA on the development board must be

configured with your project's associated SOPC Builder system. If you configured the

FPGA before running your project in the previous tutorial step, you do not have to

reconfigure the FPGA again unless you reset the board or remove power. If you need to

configure the FPGA, follow the steps to configure the hardware in the Running the Project

tutorial topic.

These sections describe how to control the flow of a debug session.

To display line numbers next to each line of code in the editor:

1. Click Preferences on the Window menu.

2. Expand General.

3. Expand Editors.

4. Click Text Editors.

5. Turn on Show line numbers.

6. Click OK.

To download executable code and start the debugger:

1. Right-click the tutorial project in the Nios II C/C++ Projects view, point to Debug

As, and then click

Nios II Hardware.

2. If the Confirm Perspective Switch dialog box appears, click Yes.

After a moment, you see the main() function of the Count Binary design in the editor.

There is a blue arrow next to the first line of code, as shown below, indicating that

execution is stopped on this line. Note that the exact line numbers might vary on your

screen.
